MACHINE FOR PREPARING PAPER-GE]? BODIES TO RECEIVE BOTTOM-HEROES.

To all whom it may concern."

- Be it known that T, nn'r F. PnovA-N- em, a citizen of the United States, residing at Melrose, in the county of Middlesex and State of Massachusetts, have invented an Improvement in Machines for Preparing Paper-(hp Bodies to Receive Bottom- Pieces, cation.

This invention relates to machines for preparing paper cup-bodies in order that bottom-pieces may be readily adhesively secured thereto. The cup-bodies are of frustoconical form and the bottom-pieces have marginal flanges, adapting them to be placed on the bodies, extended over upon the outside thereof, which flanges are adhesively secured to said bodies to secure the bottom-pieces thereto.

This invention has for its object the provision of a machine by which a line of paste or'other adhesive material may be applied to the exterior of the end-portion of the body, preparatory to having the bottomplaced thereon and secured thereto. The invention comprehends the employment of a pasting-device for accomplishing this result, which may be operated by and a rotating cup-body form. 4

Figure 1 is a side elevation of a machine for preparing cup-body forms to receive bottom-pieces embodying this invention. Fig. 2 is-a front elevation of the machine shown in Fig. 1. Fig. 3 is a of the cup-body form and pasting-roll, the latter being in engagement with a cup-body arranged on the former. Fig. 4 is a view of the cup-body having a line of paste on its lower end-portion, whereby it is prepared to receive the bottom-pieces.

10 represents the base of the machine and 12 a bracket thereon bearing an inclinedshaft 13 to the upper end .of which is secured a frusto-conical cup-body form 14, the inclination of said shaft being such that one side of the form occupies a horizontal position. Said shaft has secured to it a beltpulley 15 over which a belt 16 passes for rotating the shaft and thereby rotating the ciip or form. Such rotation of the form is continuous.

tatably supported at the forward extremity of a frame 26, which frame, as. here shown, has laterally extended gui-portions 27, 27 slidably mounted on parallel guide bars 28, 28, which provide for a reciprocating sliding movement of said frame '26 to move the pasting-roll toward and from the cup or form from the position shown in Fig. 1 to the position shown in Fig.3. Saidframehas one end of a link 30 loosely connected with it, the other end of which is loosely connected to one arm '31 of a bell-crank lever, the other arm 32 of said lever beingconnected with the upper end of a treadle-rod 33 which is connected with a, treadle 34L. Depression of the treadle acts to move the heme forward to in turn move thepasting-roll toward and placed on the form 14 and a spring 39 acts to return it to normal position. The pasting-roll is made narrow to applya line of paste of a definite width to said roll, and as the form rotates while the pasting-roll is in engagement with the cup-body thereon a narrow line of paste is hence applied to the end-portion of said cup-body. Said line of paste is usually slightly removed from the end of the cup-body, as represented in Fig. 4. The pasting-roll, when in its normal position, as represented in Fig. 1, engages a paste-supplying roll 45 which is rotatably supported in a reservoir containing paste and which is' continuously rotated by any suitable means, so faras this invention is concerned.

afrusto-conical cup body form carried by the shaft, the angular disposition of the shaft disposing the upper line of surface of the form in a horizontal plane, a carrier mounted for reciprocation on the frame and at an angle to the horizontal, and a pasting roll carried movable with the carrier to present an edge surface in a horizontal plane at all times, the movement of the carrier adjusting the pasting roll to and from contact with the form, said pasting roll remaining at all times in a position above the same.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
